Bottle 17 and base 18 are ligre 1 is a view in perspective of the display passthroughan automatic electric'flasher'switch device comprising the present invention. indicated by the reference character 14 before Figurev 2,-isI a cross-section through the device being, connected to" vthe single ,incoming power y line 15which enters'thebase.The electric flash 95 Figr "s 'a cross-section upon the line 3``3 er switch'llfis carried upon the bottom plate 16 of of Figure 2. y the base 9.

Referring again to the drawing in which the A llarge'diameter bottomless glass bottle 17 Y same reference characters refer to like parts which is provided with its own base 18, is seated ico relatively shallow large area container or basin sufficiently large in-diameter that they may enwhich may be made of sheet metalor glass, or simtirely "enclose the iive glassv electric light bulbs j ilar material, and whichwis suitably shaped to prowith their Vrespective shields which extend upvide a pleasing`v appearance from an artistic viewwardly from the basin 1. Bottle 17 is` suitably point, it being of greater length than width. Basinv secured to its base 18 in a water-tight fashion 1 05 1 is water-tight and is shown inthe drawing as and the base V18 is provided near its lower rim containing abody of fluid such as water`2, a suitwith a plurality of openings or channels which able drain 3 being provided at apoint in the Vbotare indicated'by the referencecharacters 19,4 19

tom of the said basin for the purpose of drainetc. which, instead of being provided with radial ing the water therefrom when desired. At the sides, have sides which lie diagonally to radii of -110 the bottle. Placed above these lower diagonal openings 19, 19 etc. are smaller ports, openings or air holes which are indicated by the reference characters 20, 20. A suction cleaner, indicated by the reference character 21, is carried at the top of the bottle by means of a bracket 22 which encloses the neck of the bottle at its lower end. The cleaner nozzle extends directly over the top opening in the bottle and the interior of the nozzle is directly connected to the interior of the bottle by means of a rubber plug 24 of suitable design. The incoming power lead 25 of the cleaner 21 extends around at the side of the basin 1 and into the supporting base 9 where it is connected to the electric flasher switch 14, so that current will pass through the suction cleaner when, and only when, electric current is being used by the electric lights.

In the operation of the display device constructed in accordance with the present invention upon the connection ofthe main power line Y15 to a source of velectric power the electric flasher switch 14 will cause current to enter the electric lights and also the suction cleaner motor. The interior of'bottle 17 will beilluminated in a plurality of colors, depending upon the colors `chosen for the various shields 7, 7. Upon reception of a driving current by the electric suction cleaner the motor therein will revolve and the suction-creating fan will cause air to be drawn through the nozzle 23 and exhausted into the suction cleaner dust bag. As the cleaner nozzle is directly connected through the rubber member 24 tothe interior of thek bottle 17, the result of thisrmovement of air will be the reduction in air pressure within the bottle. The resulting effeetl of' this reduction of pressure in the bottle is that the water 2, which is already present within the base 20 having entered through the openings 19,. 19, is lifted upwardly into the bottle.` The more scientific explanation is that the external atmospheric pressure exerts a greater force upon the surface of the water outside of the bottle than is exerted upon the water therein, resulting in the water being forced up intothe bottle. As the water is lifted into the bottle the water level in the basin 1 is lowereduntil finally the openings 20, 20 kare no longer below water level,

.- but 'are' exposed to the atmospherel When this relationship cornes into being, air bubbles enter through the openings 20, 20 etc., as is clearly illustrated in' Figure l, causing the water vin the bottleto be violently agitated and resulting in a very pleasing display, particularly in view of the colored lights which are Vprojected from within the body of turbulent water. The entire effect is' amplified and aided bythe fact that water in entering the bottle 17 isV given a swirling movel Y ment by the openings 19, 19 which cause-the entering water tohave a tangential rather than a radial direction of iiow. When the water has been drawn into the bottle 17 a considerable distance, thereby evidencing the surprising lifting power of the relatively small suction cleaner, and the turbulent effect has had time to be fully observed by the watchers, the flasher switch 14 automatically turns off the incoming electric current to the electric lights and to the electric cleaner. The result is that the water in the bottle 17, under the urge of gravity, immediately iiows back into the basin 1 and, before the switch 14 again. repeats the cycle, the water has reached a common level in both the bottle and basin. The entire display is artistic, interesting and educational as to the suction lifting power of the suction cleaner.

We claim:

l. In a display device, a visible body of fluid,

means to suspend a visible part of said fluid above the common level, means to create illumination' within the part so suspended, and automatic means toY render theV suspending means inactive to permit the return of said part of said fluid to the common level and to shutoff said illumination.

2. In a display device, a body of fluid, suction means to raise and suspend a part of said fluid above the common level by creating a reduced pressureY thereabove, means to direct air into the suspended partvof said water in orderyto agitate said water, and automatic means tol startV and stop said suction means.

3. In a display device, a basin, a body of fluid in said basin, a hollow column having a glass portion and open at its bottom to said body of fiuid, suction-creating means connected to said column adapted to exhaust air vtherefrom to effect the rising of said fluid therein,'and ports in said column vso positioned as tov bel below fluid level before fluid rises in Ysaid column and above fluid level in said basin aftersaid fluid ha'sAriseny a predetermined distance in said hollow column. 4. Ina display device, a shallowY basin, a body of fluid in said basin, a hollow column having a o transparent portion and open to said' iiuid, illuminating means in said column, a Vsuction cleaner connected to said column' adapted to exhaust air therefrom to effect the rising of Vsaidfluid therein, ports in said column sopositioned as to be below the fluid level in Vsaid basin before the exterior fluid rises in said column Vand above fluidv level in said basin after said fluid has risen a predetermined distance therein and to admit air into said column thereafter, and-automatic switch-means connected Vto `said illuminating means and to said suction cleaner the Vflow of power thereto.
